To a whom it may concern:

Be it known that I, ALFRED J ABEZ SIMPsoN, Jr., a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventednew and useful Improvements in Incandescent Gas-Burners, of which thefollowing is a specification.

This invention relates 'to incandescent gasburners; and theprimaryobject of the same is to provide a burner for Welsbach andotherincandescent lights with efficient and reliable means forproportionately regulating the sup-- ing the best result may be effectedwithout requiring ail-adjustment of independent mechanism or devices.

A further object of the invention is to prevent smutching or blackeningof the mantle of the burner by an irregular or improper admixture ofairand gas and also to cause the air to enter the mixing-chamber behindthegasand prevent the burner fromlighting back at the point where the gasenters the mixingchamber.

A further object is to incorporate in a burner organization a series ofcoacting elements for rendering the burner more practical and includingvalve devices connected for simultaneous operation, so that when one isopened to admit gas to the burner the other will be closed to preventthe escape of the gas through a pilot-burner, and vice versa.

With these and other objects and ad vantages in view the inventionconsists in the construction and arrangement of the several parts,

which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a side elevation of a burner embodying thefeatures of the invention and showing a mantle and part of a chimneyapplied thereto in dotted lines. Fig. 2 is a transverse vertical sectionthrough the burner. Fig. 3 is a transverse vertical section .through aportion of the burner in a plane at right angles to that shown by Fig.2. Fig. 4 is a horizontal section on the line 4 4:, Fig. 3. I Similarnumerals of reference are employed to indicate corresponding parts inthe several views.

The numeral 1 designates a gas-inlet plug or coupling bored axially forthe passage of gas therethrough and having a screw-threaded terminal forsecuring the same to a gas-feeding. means or supply. The plug orcoupling 1 communicates with a tubular T-head 2, havenlargements atopposite sides of the point of communication therewith of the plug orcoupling to form valve-seats 3 and 4, the valve-seat 3 being materiallylarger than the seat 4, and said seats respectively having mountedthereinrotatable valves 5 and 6. The valve 5, as shown, has a passage 7out therethrough at one side of the center and opening out through theperiphery thereof, said passage being straight through the valve, andthe valve 6 is formed with an arcuate passage 8, opening through itsperiphery.

The T-head at opposite ends is provided with upwardly-projectingcoupling-nipples 9 and 10, the nipple 9 being materially larger-than thenipple 10 and having a bore therethrough of the same; dimensions as thebore of the plug or coupling 1 and the head 2. The bore of' the nipple10 is reduced proportionately to the bore through a pilot-burner tube 11which is attached to said nipple and extends upan operating-lever 13,the end of said lever adjacent to the stem 12'being enlarged and formedwith a segmental slot 14," in which a projection 15, eccentrically heldby an exterior head 16, connected to the valve 6, loosely projects, theparts being so proportioned that when the lever 13 is operated to openthe valve 5 the valve 6 is closed, as shown by Fig. 2. When the lever 13is operated in a reverse direction to close the valve 5, the valve 3 isopened, the passage 8 in the latter valve being of such length that thegas will be permitted to pass therethrough into the pilotburner tube 11before the gas has been fully shut off from the burner proper by thevalve 5 in order that the pilot-burner may become ignited and so remainuntil the burner proper is to be used. The end of the lever 13 oppositethat having the segmental slot 14 therein is adapted to have a suitablepull-rod or other analogous device attached thereto, and, as in ordinaryconstructions of this kind, the pull device may depend from the burnerany distance desired.

A burner 17 of any approved type to cooperate with an incandescentmantle is used in the present instance and is embraced by a clasp 18,secured to the upper part of the tube 11. This burner has achimney-supporting rim 19 depending therefrom and an applyingtube 20,which is snugly fitted over a Bunsen tube 21, extending upwardly fromthe center of an enlargement or mixing-chamber 22 at the lower extremitythereof.

cumferentially reduced between its opposite ends to form anair-receiving chamber 24, the shell of the chamber 22 being secured tothe lower end of the plug by screw-threads, as'clearly shown by Figs. '2and 3. The upper end or head of the plug 23 is reduced to form apartition disk or flange 25, having a.

series of openings'26 extendingvertically therethrough in circularalinement around the center of said partition. The shell of the chamber22, below the position of the partition 25,'is increased in thicknessand has a plurality of reduced openings 27 formed therein to provideair-inlets, the air passing through the openings 27 into the chamber 24and then upwardly through the openings 26 into the.

threaded, as at 31, and adjustably fitted in the stem and projectingthrough the plug is a needle-valve 32, having a right-hand screwenlargement 33, engaging the threads 31, and a lower increased left-handscrew enlargement 34, the lower end of the needle-valve being providedwith a milled head 35, which is readily accessible for adjusting thevalve above the T-head 2. Communicating with the stem 28 above the upperterminal of the threads 31 is a feed-pipe 36, having a screwplug 37 inits outer end for cleaning purposes and a depending coupling-nipple 38to receive the upper end of a connecting-pipe 39,

A plug 23 is projected upwardly into the chamber 22 through the lowerend of the latter and is cir-' The lower part of the bore through thestem 28 is Screwwlhich is attached at its lower end to the nipp e 9.

Projecting outwardly from the stem 38 at a point slightly below thelower end or head of the plug 23 are diametrically-opposed guidearms 40,having vertical openings 41 extending through their outer ends, in'which sliderods 42 have movement and'are secured at their lower ends tothe opposite extremities of a yoke 43, which engages the left-hand screwenlargement 34 of the needle-valve. The upper ends of the slide-rods 42are secured in sockets 44 at diametrically opposite points on acontrolling-sleeve 45, slidable over the exterior of the lower extremityof the shell of the mixing-chamber 22 and adapted to regulate the openand closed condition of the air-inlet openings 27. By turning theneedle-valve 32 in opposite directions it will be adjusted'to admit moreor less gas into the mixing-chamber 22 when the valve 5 is open, andsimultaneously with this adjustment of the needlevalve thecontrolling-sleeve 45 will be moved to regulate a proportionateadmission of air into the air-receiving chamber 24. The advantage ofthis unity of adjustment and control of the admission of air and gas isthat the right proportions of both air and gas will be at all timesadmitted to the mixing-chamber 22, it being understood that in thepreliminary arrangement of the parts the sleeve 45 and needle-valve willbe positionedto obtain a proper admixture of air and gas. Anotheradvantage resident in this simultaneous and proportionate adjustment isthe absolute impossibility of admitting more air than necessary andretarding complete combustion and a consequent smutching or blackeningofthe mantle. By having the gas enter the mixing-chamber ahead of theair ignition of the gas in the mixing-chamber or lighting back isprevented. Furthermore, the adjustment of the needle-valve and theadmission of air may be carried on without modifying the How of gas tothe stem 28. i

The improved burner will be found exceptionally advantageous in use andmore economical in the use of gas and mantles.

Itwill be understood that changes in the proportions, dimensions, andminor details may be resorted to without departing from thespirit of theinvention.
